Africa dwarfs Mozambique: about 30,370,000 km² km² against 790,643 km² km². At true size Africa is about 38.4× larger — the whole of Mozambique fits into Africa roughly 38 times.
The old Mercator map treated both about equally (1× vs 1.1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Mozambique fits 38× into Africa.
